The subject of the course is the regulation of war violence and the ways in which this can be achieved: by formulating rules for the declaration and conduct of war through the theory of Just War, by legitimizing certain forms of war and delegitimizing others, in conjunction with the type of state that prevails in each historical era, and by completely denouncing war in the context of a pacifist protest. Particular emphasis is given to historically diverse Christian attitudes towards the idea of a Just War.
